10 inches bass driver active subwoofer

The mid-sized Kube 10b has a sealed cabinet, 10 inches bass driver and 300 Watts to produce serious extension and control. The latest addition to KEF's powerful range of subwoofers opens up sound’s hidden depths thanks to 300 Watts of Class D power integrated with a 10 inches driver and iBX dynamic bass extension technology.

Hear new dimensions in sound with Kube subwoofers

The Kube 10b effortlessly unleashes explosive power. iBX technology extends the bass depth dynamically and KEF’s unique ability to design, build and integrate the driver in-house takes optimisation to a whole new level. Delivering immersive music and home theatre sound that takes you to the heart of the performance.

Immersiveness

Go deep or go home. KEF’s design and engineering team worked in chorus to develop iBX. This Intelligent Bass Extension algorithm creates an extended depth that unlocks the full potential of the custom driver. Giving you unparalleled precision and ultimate synchronicity between amplifier, driver and sealed cabinet.

Easy configuration

Kube subwoofers offer unmatched set up flexibility. A range of LFE, line and speaker-level inputs, phase selection and DSP controlled EQ settings help you get the best from a Kube. Put it in a convenient place, match it to any main speaker or type of music system and start exploring new depths in the sound.

Integration

KEF is quite possibly the only high-end manufacturer that designs, engineers and assembles the driver, cabinet and circuitry in-house. This level of integration means we are committed to pure sound and the Kube stays true to that ideal. The result is a driver and amplifier that are perfectly in tune.

Powerful!
Color: Lux Galaxy, Size: Rechargeable Z1 Motor Max
This thing is powerful and works great! I was hesitant about some of the negative reviews, but this is worth it so far. I use it every day and haven't charged it in the week that I've had it. Some people complained about turning it off.... It's not that hard. Just hold the button down for a second or two and it shuts off, no fuss. If you tap/press the button you'll cycle through the next speed and then off. I only use the first speed to make my protein shake and matcha. I feel like the high speed would just whip everything to pure foam! I'm hoping this lasts me a long time.

Quiet and Effective frother/mixer and Terrific Customer Service
Zulay Kitchen Powerful Milk Frother Wand We ordered two Zulay frother wands and after just several months of continuous usage one of the units stopped working and the other one was sporadically working, where sometimes it would run “full power” and at other times it was barely spinning or turning the beverage. I called Zulay and gave them my Amazon order number. After the Customer Service rep walked me through some minor things to check on the units she was also convinced that the units were probably defective. She had a replacement sent from Zulay along with a mini as a bonus for our troubles! And she had Amazon ship the other replacement unit. Both shipments arrived promptly within days and we have been using them for months now without any major issues. We use the units (the two “standard” wands) almost every day and they get used two to three times a day. They only take ten to twenty seconds to mix up cocoa powder, hot or cold. And the same goes for different protein powder shakes. What I especially like about these units is that there have been many times when I have had to use them off-hours, like between 5:00 and 6:00 AM. They are Whisper quiet so nobody gets disturbed. One generally can’t do this level of quiet stirring/mixing with a kitchen hand blender/mixer or shake blenders. These Zulay mixing units have really come in “handy” for us. We are very Grateful to Amazon for their prompt delivery, and especially to the Customer Service representative at Zulay for her help, and to Zulay for standing behind their products and providing us with terrific and prompt Customer Service! Thank you! Cheers! November 3, 2025

Great look and very powerful - consider what your wanting to froth/mix - may be too powerful
Color: Lux White, Size: Rechargeable Z1 Motor Max
It's a great frother - but more for large drinks. Very powerful, even on the low speed. I returned it because I want something to mix my collagen and creamer in my coffee. The first time I turned it on it shot half the coffee out of the cup - very powerful. It has a great look, sleek and fits easy in the hand - but for what I needed, two powerful. It would have been nice to have a fully adjustable speed wand like my replaceable battery powered frother.
